B) Brazilian highlands and the Patagonian plateau
C) Guiana highlands and the Brazilian highlands
D) Guiana highlands and Andes mountains

Answer 1

Hint: The Amazon River is a vast, intricate water system that runs through the Amazon rainforest in South America, one of the world's most important and complex ecosystems. It is the world's largest river in terms of water flow and the disputed second-longest river.

Complete answer:
The Amazon River and its tributaries provide water to the Amazon Basin in South America. The Amazon rainforest, also known as Amazonia, covers the majority of the basin. The Amazon River System transports the most water of any river system, accounting for roughly 20 percent of all water transported to the oceans by rivers.

Before the Andes formed, the Amazon basin flowed west to the Pacific Ocean, forcing the basin to flow east to the Atlantic Ocean. The basin is divided politically into Peruvian Legal Amazonia, Brazilian Legal Amazonia, Colombia's Amazon region, and parts of Bolivia, Ecuador, and Venezuela's Amazonas state.

From the Brazilian Highlands in the south to the Guiana Highlands in the north, the Amazon River basin extends. It occupies nearly half of South America and includes eight countries: Colombia, Bolivia, Guiana, Ecuador, Peru, Brazil, Venezuela, and Suriname, with a total area of about 2.7 million square miles.
The Amazon river basin lies between the Guiana highlands and the Brazilian highlands.

Additional Information: The Amazon plays the part of a sink, removing heat-trapping carbon dioxide from the atmosphere. At the moment, the planet emits approximately 40 billion tonnes of carbon dioxide into the atmosphere per year.

Thus the correct answer is option ‘C’.

Note: The Amazon River basin has a dry season and a rainy season, during which the rivers flood the low-lying forests next to them. The basin's atmosphere is normally hot and humid. The Amazon consumes 2 billion tonnes of carbon dioxide per year (or 5% of annual emissions), making it a critical component of climate change mitigation.
